Mn[Cu(L)(O 2 CMe) 2 ] · H 2 O (L = N,N’-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane) was synthesized and the crystal structure determined. (C 23 H 26 CuMnN 2 O 8 ).H 2 O, monoclinic, space group P2 1 /c, a = 12.017(3), b = 8.217(3), c = 24.786(4) Å , β = 92.10(2)°, V = 2446(1) Å 3 , Z = 4. The crystal structure consists of ordered dinuclear units with Cu II  and Mn II  ions bridged by two oxygen atoms of the Schiff base ligand. The Cu II  coordination sphere is a slightly distorted square-plane formed by the N 2 O 2  donor set of the Schiff base ligands. The average Cu-O and Cu-N distances are 1.920(1) and 1.957(4) Å , respectively. The coordination around the Mn II  ion is a distorted tetrahedron with the donor oxygen atoms of the Schiff base ligands and oxygen atoms of the acetate anions. The Cu ··· Mn separation is 3.327(4) Å . There is also one non-coordinating water molecule in the crystal structure. The χ and χT versus T plots, χ being the molar magnetic susceptibility per Cu II Mn II  unit and T the temperature, has been measured in the 4.9 - 301 K temperature range. The values of the interaction parameters are J = −28.3 cm −1 , g Mn  = 2.01, g Cu  = 2.07. This indicates an intramolecular antiferromagnetic interaction between Cu II  and Mn II  ions.
